Two non‐amphiphilic star‐shaped 2,4,6‐tris(1,2,3‐triazol‐4‐yl)‐1,3,5‐triazines showing different behavior in terms of self‐assembly and luminescent properties are described. They aggregate in the liquid phase to form low‐dimensional nanostructures with a variety of morphologies, such as spherical particles, one‐hole hollow spheres, toroids, twisted fibers or helical nanotubes, just by varying the conditions of a straightforward reprecipitation method. Aggregation has an opposite effect concerning the fluorescent properties of the proposed compounds, either causing the enhancement or the quenching of the emission after the self‐assembly. Quantum chemical calculations have been also performed to assist in the structural and electronic characterization of the two star‐shaped compounds.
